Jimmy Xiang commented on HBASE-11756:
-------------------------------------
Not that. It's about the notification for those AssignmentListeners. For, AM has its own regionOffline
method, in which it calls sendRegionClosedNotification(). Sometimes, RegionStates#regionOffline
is called directly so the notification call is not invoked.

> In AssignmentManager, notifications are triggered when regions are opened/closed. However,
notifications are not always triggered. For example, when a server is dead, regions are closed
implicitly, and no notifications are triggered.
> Is it a better place to trigger such events in RegionStates?
